Which type of technology can prevent malicious software from monitoring user activities, collecting personal information and producing unwanted pop-up ads on a user computer?

Antispyware
Two factor authentication
Password manager

Firewall

Answers Explanation & Hints:

Antispyware is the type of technology that can prevent malicious software from monitoring user activities, collecting personal information, and producing unwanted pop-up ads on a user’s computer. Antispyware software is designed to detect and remove spyware, adware, and other malicious software that can compromise a user’s privacy and security. It works by scanning a computer’s files, registry, and memory for known spyware and adware programs and removing them. In addition, some antispyware programs also offer real-time protection, which can block new spyware and adware from being installed on a computer.

Two-factor authentication, password managers, and firewalls are also important security measures, but they do not specifically target spyware and adware. Two-factor authentication is a method of authentication that requires two forms of verification before granting access to a system or account. A password manager is a software application that helps users generate and manage strong passwords for their various accounts. A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

What should you do in order to make sure that people you live with do not have access to your secure data?

Set up password protection
Install antivirus software
Increase the privacy settings on your browser

Turn on a firewall

Answers Explanation & Hints:

To make sure that people you live with do not have access to your secure data, you should set up password protection. This can include setting up passwords on your devices, user accounts, and any files or folders that contain sensitive information. Make sure to use strong passwords that are difficult to guess, and consider using two-factor authentication for an extra layer of security.

Installing antivirus software and turning on a firewall can also help protect your data, but they primarily protect against external threats from the internet. They do not protect against threats from people who have physical access to your devices or home network.

Increasing the privacy settings on your browser can also help protect your data when you are online, but it does not protect your data when you are offline or when others have access to your devices.

In summary, setting up password protection is the most important step you can take to protect your data from people you live with. Additionally, installing antivirus software, turning on a firewall, and increasing the privacy settings on your browser can provide additional layers of protection against external threats.

Why do IoT devices pose a greater security risk than other computing devices on a network?

IoT devices cannot function on an isolated network with only an Internet connection
Most IoT devices do not receive frequent software updates
IoT devices require unencrypted wireless connections

Most IoT devices do not require an Internet connection and are unable to receive new updates

Answers Explanation & Hints:

IoT (Internet of Things) devices pose a greater security risk than other computing devices on a network for several reasons, including:

Most IoT devices do not receive frequent software updates: Unlike computers and smartphones, which receive regular software updates to address security vulnerabilities and other issues, many IoT devices do not receive frequent updates. This means that vulnerabilities and other security issues may go unaddressed for long periods of time, leaving the devices and the network they are connected to vulnerable to attacks.
IoT devices require unencrypted wireless connections: Many IoT devices are designed to connect to wireless networks using unencrypted connections, which means that data transmitted between the device and the network can be intercepted and accessed by hackers. This can include sensitive information, such as passwords and personal data.
IoT devices cannot function on an isolated network with only an Internet connection: Unlike other computing devices, many IoT devices require a connection to the internet in order to function. This means that they are more vulnerable to attacks from external sources, as they are constantly connected to the internet and may not have the same security protections as other devices on the network.
Many IoT devices do not require an internet connection and are unable to receive new updates: While some IoT devices require an internet connection in order to function, others do not. However, even devices that do not require an internet connection may still be vulnerable to attacks if they do not receive regular updates and patches to address security issues.
Overall, the lack of security updates, unencrypted wireless connections, and the constant need for an internet connection make IoT devices a greater security risk than other computing devices on a network.

Which of the following is an example of two factor authentication?

Your account number and your name
Your answer to a general knowledge question and your password
Your fingerprint and your password

Your password and your username

Answers Explanation & Hints:

Your fingerprint and your password is an example of two-factor authentication. Two-factor authentication is a security process that requires two forms of identification before granting access to a system or account. In this case, the two factors are something you know (your password) and something you have (your fingerprint). This adds an extra layer of security, as even if someone has your password, they still would not be able to access your account without your fingerprint.

The other options listed are not examples of two-factor authentication. Your account number and your name, your answer to a general knowledge question and your password, and your password and your username all rely on just one form of identification, which is something you know.

How can you keep your personal browsing history hidden from other users on a shared computer?

Reboot the computer after closing the web browser
Move any downloaded files to the recycle bin
Operate the web browser in private browser mode

Use only an encrypted connection to access websites

Answers Explanation & Hints:

You can keep your personal browsing history hidden from other users on a shared computer by operating the web browser in private browsing mode. Private browsing mode, also known as incognito mode in some web browsers, is a feature that allows you to browse the web without saving any data from your browsing session. This includes cookies, browsing history, and form data. When you close the private browsing window, all of this data is automatically deleted, so there is no trace of your browsing session left on the computer.

Rebooting the computer after closing the web browser or moving downloaded files to the recycle bin will not hide your browsing history. Rebooting the computer will not delete your browsing history or any other data saved on the computer, and moving downloaded files to the recycle bin will only remove them from the desktop or downloads folder – they can still be accessed by other users on the computer.

Using only an encrypted connection to access websites can help protect your privacy and security while browsing, but it will not hide your browsing history from other users on the same computer. Encrypted connections ensure that the data you send and receive while browsing the web is secure and cannot be intercepted by hackers, but they do not affect what data is stored on the computer itself.

You are looking to print photos that you have saved on a cloud storage account using a third-party online printing service. After successfully logging into the cloud account, you are automatically given access to the third-party online printing service. What allowed this automatic authentication to occur?

Your account information for the cloud storage service was intercepted by a malicious application
You are using an unencrypted network which allows the password for the cloud storage service to be viewed by the online printing service
The cloud storage service is an approved application for the online printing service

The password you entered for the online printing service is the same as the password you use for the cloud storage service

Answers Explanation & Hints:

The cloud storage service is an approved application for the online printing service, which allowed for the automatic authentication to occur. When two online services have a pre-existing partnership and authorization, they can allow automatic authentication for the user. This means that once the user logs into one service, they can automatically be logged into the second service without the need to enter their credentials again. In this case, since the cloud storage service is an approved application for the online printing service, it has the necessary permissions to authenticate the user and grant access to the online printing service.

The other options listed are not likely scenarios that allowed for the automatic authentication to occur. If your account information for the cloud storage service was intercepted by a malicious application, the attacker would not be able to authenticate with the online printing service. If you were using an unencrypted network, your password could potentially be intercepted, but this would not allow for automatic authentication. If you entered the same password for both services, this could allow for authentication, but it would not be automatic authentication.

Which of the following is a requirement of a strong password?

Use a dictionary word or a common statement that you’ll remember
Use at least six characters

Use special characters such as ! @ or $

Answers Explanation & Hints:

Using special characters such as ! @ or $ is a requirement of a strong password. A strong password should include a combination of upper and lowercase letters, numbers, and special characters. This makes the password more complex and harder for attackers to guess or crack through brute force attacks.

Using a dictionary word or a common statement that you’ll remember is not a requirement of a strong password. In fact, this can make your password weaker, as attackers often use dictionary attacks to guess passwords based on common words or phrases. It’s recommended to use a combination of random words or phrases, or to use a password manager to generate and store strong, unique passwords for each account.

Using at least six characters is also not a requirement of a strong password, as a longer password is generally considered more secure. The National Institute of Standards and Technology (NIST) recommends using passwords that are at least 8 characters long, but ideally 12 or more characters.

Which of the following passwords would most likely take the longest for an attacker to guess or break?

drninjaphd
10characters
super3secret2password1

mk$$cittykat104#

Answers Explanation & Hints:

The password “mk$$cittykat104#” would most likely take the longest for an attacker to guess or break because it includes a long combination of upper and lowercase letters, numbers, and special characters. The password has a mix of different character types and is 16 characters long, making it very difficult for an attacker to guess or crack through brute force attacks.

The passwords “drninjaphd”, “10characters”, and “super3secret2password1” are relatively weak passwords and could be easily guessed or cracked by attackers using common methods. “drninjaphd” and “10characters” are both short and use common words or phrases that can be easily guessed through dictionary attacks. “super3secret2password1” is longer and includes some special characters, but still uses common words and is not complex enough to be considered a strong password.

In general, it’s best to use long, complex, and unique passwords for each account, or to use a password manager to generate and store strong passwords.

Which configuration on a wireless router is not considered to be adequate security for a wireless network?

Preventing the broadcast of an SSID
Enabling wireless security
Implementing WPA2 encryption

Modifying the default SSID and password of a wireless router

Answers Explanation & Hints:

Preventing the broadcast of an SSID is not considered to be adequate security for a wireless network. While disabling SSID broadcast can make the network less visible to attackers, it does not provide any significant security benefit, as the SSID can still be easily discovered through other means.

Enabling wireless security and implementing WPA2 encryption are both important steps to securing a wireless network. Wireless security protocols such as WPA2 use encryption to protect the wireless traffic from interception or eavesdropping, making it more difficult for attackers to capture sensitive information.

Modifying the default SSID and password of a wireless router is also an important step to securing a wireless network. Using the default SSID and password makes it easier for attackers to gain access to the network, as they can easily find information about the default settings of the router online. Changing the default SSID and password to a unique and complex value can make it more difficult for attackers to guess or crack the password and gain access to the network.

In general, securing a wireless network requires a combination of different security measures, including strong encryption, unique and complex passwords, and proper configuration of the wireless router.

What is the best method to prevent Bluetooth from being exploited?

Always disable Bluetooth when it is not being used
Always use a VPN when connecting with Bluetooth
Only use Bluetooth to connect to another smartphone or tablet

Only use Bluetooth when connecting to a known SSID

Answers Explanation & Hints:

The best method to prevent Bluetooth from being exploited is to always disable Bluetooth when it is not being used. Keeping Bluetooth turned off when it’s not needed can prevent attackers from exploiting vulnerabilities in the Bluetooth protocol, such as Bluejacking, Bluesnarfing, or Bluebugging. Attackers can exploit these vulnerabilities to gain unauthorized access to a device, steal data, or remotely control a device.

Using a VPN when connecting with Bluetooth or only using Bluetooth to connect to another smartphone or tablet are not effective methods to prevent Bluetooth exploitation, as they do not address the underlying vulnerabilities in the Bluetooth protocol. VPNs are designed to provide secure communication over untrusted networks, and while they can provide an additional layer of security, they do not address the fundamental issues with Bluetooth security. Similarly, limiting Bluetooth connections to known SSIDs or devices can help reduce the risk of unauthorized access, but it does not address the root cause of Bluetooth vulnerabilities.

In summary, the best way to prevent Bluetooth exploitation is to turn off Bluetooth when it’s not in use. If Bluetooth needs to be used, it’s recommended to keep the device’s firmware and software up-to-date, use strong and unique passwords or passphrases, and avoid pairing with unknown or untrusted devices.

Which technology removes direct equipment and maintenance costs from the user for data backups?

A tape
A cloud service
Network attached storage

An external hard drive

Answers Explanation & Hints:

A cloud service removes direct equipment and maintenance costs from the user for data backups. Cloud backup services allow users to store their data securely on remote servers operated by third-party providers, eliminating the need for users to maintain their own backup hardware or infrastructure. The cloud service provider is responsible for the maintenance, security, and upkeep of the backup infrastructure, which reduces the workload on the user’s end and provides a more reliable and scalable backup solution.

While tape backups, network attached storage, and external hard drives are all viable backup solutions, they typically require direct equipment and maintenance costs from the user. Tape backups and network attached storage require dedicated hardware and software, while external hard drives may require periodic upgrades and maintenance to ensure reliability and data integrity. Cloud backup services, on the other hand, can provide users with a cost-effective and scalable backup solution without the need for direct equipment or maintenance costs.

You have stored your data on a local hard disk. Which method would secure this data from unauthorized access?

Two factor authentication
Duplication of the hard drive
Data encryption

Deletion of sensitive files

Answers Explanation & Hints:

Data encryption is a method that can secure data stored on a local hard disk from unauthorized access. Encryption involves converting the plain text data into a coded format that can only be accessed by authorized users who have the encryption key. This process makes it difficult for unauthorized users to access the data even if they gain physical access to the hard disk.

Two-factor authentication can provide an additional layer of security by requiring the user to provide a second authentication factor, such as a code generated by a mobile device, in addition to a password. However, it does not protect the data stored on the hard disk itself.

Duplication of the hard drive can provide redundancy and protect against hardware failure, but it does not protect against unauthorized access to the data stored on the hard disk.

Deletion of sensitive files can help protect against unauthorized access to specific data, but it does not provide comprehensive protection for all data stored on the hard disk.

Therefore, data encryption is the most effective method to secure data stored on a local hard disk from unauthorized access.

You are having difficulty remembering passwords for all of your online accounts. What should you do?

Write the passwords down and keep them out of sight
Save the passwords in a centralized password manager program
Create a single strong password to be used across all online accounts

Share the passwords with a network administrator or computer technician

Answers Explanation & Hints:

It is generally not recommended to write down passwords or share them with others, as this can increase the risk of unauthorized access to your accounts. Creating a single strong password to be used across all online accounts is also not recommended, as if one account is compromised, then all accounts become vulnerable.

The best solution is to use a centralized password manager program, which securely stores and manages all of your passwords in an encrypted format. A password manager program can generate strong and unique passwords for each account, and automatically fill in the login credentials when you visit the site.

Using a password manager program helps reduce the risk of unauthorized access to your accounts by ensuring that each password is unique and strong, and by protecting your passwords with encryption. It also makes it easier to manage and remember your passwords, as you only need to remember one master password to access the password manager program.

How can you prevent others from eavesdropping on network traffic when operating a PC on a public Wi-Fi hotspot?

Disable Bluetooth
Use WPA2 encryption
Connect with a VPN service

Create unique and strong passwords

Answers Explanation & Hints:

To prevent others from eavesdropping on network traffic when operating a PC on a public Wi-Fi hotspot, it is recommended to connect with a Virtual Private Network (VPN) service. A VPN creates a secure, encrypted connection between your device and the VPN server, which helps to prevent others from intercepting and viewing your network traffic.

Using WPA2 encryption is also a good security measure to protect your network traffic, but it only encrypts the communication between your device and the Wi-Fi hotspot. It does not protect your data beyond the Wi-Fi hotspot or prevent others on the same network from eavesdropping on your traffic.

Disabling Bluetooth is not directly related to preventing eavesdropping on network traffic, as Bluetooth is a different type of wireless connection that is used for short-range communication between devices. However, it is still a good security practice to disable Bluetooth when it is not in use to prevent unauthorized access to your device.

Creating unique and strong passwords is important, but it does not directly address the issue of eavesdropping on network traffic. It is still important to use strong passwords to protect your accounts from unauthorized access.

What is the only way of ensuring that deleted files on your computer are irrecoverable?

Physically destroying your computer’s hard drive
Using a software program such as SDelete or Secure Empty Trash

Emptying your computer’s recycle bin

Answers Explanation & Hints:

The only way of ensuring that deleted files on your computer are irrecoverable is by physically destroying your computer’s hard drive. This method ensures that the data stored on the hard drive is completely destroyed and cannot be recovered by any means.

Using a software program such as SDelete or Secure Empty Trash can help to overwrite the data on the hard drive and make it more difficult to recover the deleted files. However, these methods do not guarantee that the data is completely irrecoverable, as there are still techniques that can be used to recover overwritten data.

Emptying your computer’s recycle bin only removes the file reference from the file system, which makes the file space available for other data to be written on top of it. However, the actual data of the file still remains on the hard drive until it is overwritten by other data. This means that it is possible to recover the deleted files using data recovery software, especially if the files were not securely deleted.
